martinthoma / banana-gym Goto Github PK

Would be cool to see a simple A3C work with this environment.

I am getting the following error when i call env = gym.env('Banana-v0')

AttributeError: 'BananaEnv' object has no attribute '_seed'

Full code:

import gym
import gym_banana

def run():
  env = gym.make('Banana-v0')
# run()

if __name__ == '__main__':
  run()
# done

Full traceback :

Traceback (most recent call last):
  File "example_banana.py", line 16, in <module>
    run()
  File "example_banana.py", line 10, in run
    env = gym.make('Banana-v0')

You need to reset the current step otherwise this environment is doing nothing.

I tried to install gym_banana in colab, but I'm getting a ModuleNotFoundError. I tried different ways..
Frist try:
!git clone https://github.com/MartinThoma/banana-gym.git
python ./banana-gym/setup.py install -e

Second try:
!pip install gym_banana

Both ways seem to work:

I restarted the runtime then tried to import it in another cell:

import gym
import gym_banana

ModuleNotFoundError Traceback (most recent call last)
in ()
1 import gym
----> 2 import gym_banana
3 #env = gym.make('Banana-v0')

ModuleNotFoundError: No module named 'gym_banana'
